. anv arrangement whereby tlic afcurac ot l..

speed measuring or indicating apparatus is subject to and dependent upon the derangenients ot and defects developed in. the tron;

icc Y tained. thereby.

It is among thespecial 4purposes of our -pres'entinvention to provide a speed measfuring and indicating mechanism for use on railway and other cars which is in the form of` an independent attachment capable .of

being readily applied -to or removed fromacar truckwithout interfering with or being deranged by the truck axley or wheels, andl i which maybe'operated'solely by .the pro ession ofthecar and not from the wheel or axle,- and hence, ,an apparatus which is wholly, free' from. thefinaccuracies andimpairments due to the wear of wheel treads,

`ljirake shoe applications, hot boxes or other derangeinents of the rough usage of service.l

In carrying out our invention we propose nto, 'locate the speed measuring or indicating device at a convenient pointin a car and to 'drive the Isaine through transmitting gearing driven from a trolley or drive wheel adapted to contact with a track rail and to. be rotated thereby 'as lthe car progresses therealong. ,f j :"we also propose to supportsuch trolley f am,

inea-ns for yieldingly pressing the trolley trolleywheel is rotated in one direction or We also proposeA to provide wheelinto ontact with the track rail wherebythe rotations of. suchtrolley wheel are ,assured but without imposing undue wear. thereon.

,Wef'also propose to provide etticient means for lubricating the gearing and for preventing the access of grit, dust or dirt thereto. These various objects and purposes may be'accomplished in a wide variety of specific While,

now describe one form of 'mechanism as illustrative of an operative 'embodiment'of the principles of our invenand the best form in which we at ,l 'presentconteinplate carrying our invention into practical operation, still we do not desire'tobeunderstood as meaning that our the exact form of construction and arrange- 'ment shawn. 4 y

Referring to l detachably bolted or'v'otherwise secured to therefore, we have E N. r1`he bevel gears 8 and 9 being respecinvention is to be' limited or` restricted to- B, is a bracket or hanger adapted to be or free end ofthe anglearm C, is bent or deflected laterally, as indicated at. li`,and has secured thereto by bolts or otherwise, a casting having ahollow cylindrical hub portion G, and a hollow cylindrical casing H, arranged, in the particular form shown, in right angular relation with respect' tofthe hub portion. The-'trolley wheel J, is jour-I naled to .revolve upon .the hub port-ion G. lf 'desired' a sleeveA or lining il, of soft metal or other bearing material, may be in# terposed between the 'bearing surfaces` of the interior of the trolley wheel and the ex'- `terior of the hub' portion G. lVithin the bore of the hub portion G, is a bearing sleeve L, in which is journaled a shaft M, having one Yend arranged to extend' transversely into the casing H, and carrying a bevel gear N. The rotations of thetrolley wheel J, may beiniparted tothe shaft vM, in any suitable or' convenient manner. XVe have shown a simple arrangement wherein a cap O, is arranged to be detachably connected to the hub of the trolley wheel J, and having a split boss l), at thev axial center thereof, said split boss arranged and adapted to receivea nib or projectionrR, on the end of shaft M. This shaft is journ led in the` geometrical axis of the hub portion Gr and hence, also, in the geometrical axis of the trolley wheel and consequently, when the cap O, is applied, as clearly shown iii Fig. Q, the rotations of the trolley wheel are transmitted to the shaft M, and the two revolve together in whichever direction the trolley wheel may rotate. Thecap O, also serves the purpose of excluding dust, dirt, grit or the like from 'the bearings of said wheel and shaft. Arranged within the portion or casing H, on opposite Sides of the end of shaft M, and the bevel gear N, thereon are bearing blocks 4, 5. In each of these bearing blocks is journaled to rot-ate a hollow shaft 6, 7, arranged inl axial alinement with each other. On the proximate ends of shafts 6, 7, are mounted or formed bevel gears 8,9, respectively, said gears meshing with and driven by bevel gear tively arranged on opposite sides of gear JN, said shafts 6 and 7, are rotated in opposite directions with respect to each other. Ex-

tending longitudinally through the axially alined bores of shafts 6 and 7, is a shaft 10, to the respective ends of which are fixed or secured the oppositely presented blocks 11, 12, constituting members of clutches.` The other members of the clutches comprise .disks or rings i3, 14;, respectively fixed or secured to the hollow shafts 6, 7, and respectively cooperating with the clutch members 11, 12. ln each ring or disk 13, 14e, are formed tapering grooves 15, see Fig. 8, said grooves being tapering in depth, and each adapted to receive a ball 16, said balls being interposed between the juxtaposed surfaces of blocks il, or 12, and their coperating disls or rings 13, 14s. The grooves l5 in the one ring or disk 13, extend in reverse direction with .y .reference to the grooves yin the other ring or disk 14. Y From this descriptionr it will be seen that when a ring or disk 13, M, is revolved in a direction to crowd the balls 16 toward the narrow or shallow parts of the grooves l5, ldsald balls are thereby pressed `against the coperating clutch member 11- or l2, as the 'case Amay be, While', since the other shaft 6 or 7 is always revolved in the opposite direction, the balls 1.6 in the grooves of the. other 15 ring or disk "are crowded toward the Wider or deeper parts of" their grooves, thereby releasing the engagement with their cooperating clutch member, and consequently the shaft 10 is rotated in acontinuous direction, whether driven from hollow shaft 6 or vfromholloyv shaft 7 In other Words, shaft l() is always driven in the saine direction whether the trolley Wheel J is rotated in one' direction or the other.l 4The casing l-l, is 'provided Withend caps 17, 18, which closetheends of said casing thereby pre# `venting access of dust, dirt or the like to :the gearing shaft bearing/ and clutch mechanisms, above described. 3'()IV It is'obvious that many other forms of clutch mechanism may be employed vvith-` out departure from the spirit or sco-pe of our invention. The form shown, however,

-iswell adapted for our purposes. i' "'.One end of shaft l0, is provided With a nib'19, adapted to be'received in a split boss. 20, forming the 'terminal connection of a flexible transmitting gear or shaft 2l, housed with a suitable sheathing 22, and leading to the speed measuring or indicating instrument 23, on the car.- lf desired, the transmitting gear or its sheathing may be passed through a sleeve orguide 2i, fixed upon or ,secured to the bracket B.

- lf desired, andin order to .efficiently lubricate the drive gearing and bearings of the various revolving parts thereof, oil may be vsupplied l,to the interior of casing .ll in any suitable or convenient manner. f' have shown an oil cup 25, deliverin.'

the casing- H, for this purpose and I ing oil to all the bearings in said ing aswell as to the `bearings in the hub portion G, the caps 0,17 and 1S, serving to retain the lubricating oil Within said casing and' hub. Itis desirable' that the trolley Wheel d, be yieldingly maintained in contact with the track rai indicated at'QG, Fig. l, and this result We arrange a tension upon the gi... urn? C, and con g to roclt or swing said angle pivot pin l), in a direction to .ss 'the trolley 'wheel into con '.clt The spring 27 is carried upon a bolt 28, and its tension is adjusted by means of a fnut 29, carried vby the bolt and against which one end of the spring 27 bears, the other end of the spring hearing against the end of angle arm C.

While We have shown the trolley Wheel J,

' arranged to bear against the track rail 26,

and While we prefer such arrangement, still our invention is not limited in this respect as it is obvious that the said Wheel may bear against the tread of a truck wheel, if so desired.

From the foregoing description it will be seen that We provide an exceedingly simple Iand elicient speed measuring or indicating mechanism in the form of an attachment which can be vreadily applied to a truck frame and which is independent in its operation of the axle or other part of the car driving mechanism and wherein the accuracyof the speed indicating or measuring device is notimpaired by Wear of the truck Wheels, wherein the speed of the car may be accurately measured or indicated whether thecar moves in one direction or the other,
